Photographic camera having electric motor drive for shutter cocking and film winding

Abstract

A photographic camera having a mirror gearing and an electric motor for shutter cocking and film winding, in which the current connection for the electric motor situated in the camera housing is controlled alternately by the shutter and film winding. The camera includes a manual release mechanism and a remote release mechanism. A detent disc is mounted on a shaft and driven by the electric motor. A release lever is also mounted on the shaft. A first blocking lever is provided for inhibiting the movement of the release lever and is connectable both with the manual release and the remote release. A second blocking lever also inhibits the movement of the release lever. A detent lever with a nose thereon engages the detent disc and is connected through a joint with the second blocking lever. An actuator lever is provided for releasing the detent lever from the detent disc and is blockable by a blocking pawl coupled with the mirror gearing. A dog is driven by the motor for tensioning the actuator lever. The motor drives the detent disc causing the release lever to be held under tension by the first and second blocking levers. When the cocking cycle is completed the detent lever drops into the detent disc and releases the second blocking lever, the motor being simultaneously switched off. On actuation of the release the first blocking lever is moved liberating the release lever which activates the mirror gearing and the shutter. After release of the shutter the mirror gearing actuates the blocking pawl which releases the detent lever from the detent disc causing the motor to operate and recock the release lever.
